参考图1，本发明提供了一种除尘机10，该除尘机10能够吹气或吸气，以对狭小空间，例如一些精密仪器内部零部件的拐角位置的灰尘等污垢进行清除，可以通过吸气将灰尘吸附至除尘机10内，或者吹气将灰尘吹落。
参考图1和图2，除尘机10包括除尘机外壳101和风机组件600，该除尘机外壳101包括主体100和手柄200。主体100具有能够供气流通过以实现吹气或者吸气的风嘴110，风嘴110的数量可以为一个或者两个及以上，例如图中示意了风嘴110的数量为一个，该风嘴110设置于主体100的一端。手柄200与主体100连接，手柄200的长度延伸方向与主体100的长度延伸方向呈夹角设置，以便于人手握持手柄200来方便用户对主体100的使用。
手柄200能够相对主体100转动，以使手柄200能够定位在第一位置和第二位置。当手柄200在第一位置时，手柄200的中心轴方向与主体100的某一端的吹气或吸气方向呈钝角设置，当手柄200在第二位置时，手柄200的中心轴方向与主体100的另一相对端的吹气或吸气方向呈钝角设置。手柄200的中心轴、主体100的中心轴及手柄200与主体100转动的旋转轴位于同一平面内；或者，手柄200的中心轴运动的轨迹形成锥面的至少一部分。
需要理解，在其它实施例中，手柄200与主体100固定连接且不能相对转动。
风机组件600设置于主体100内，风机组件600包括电机610以及与电机610连接的叶轮，电机610能够带动叶轮转动，以驱使主体100的风嘴110吸气或吹气。如图2所示，在一实施例中，主体100设置有第一通气口111和第二通气口121，主体100内部设置有通气腔102，第一通气口111和第二通气口121皆连通通气腔102和主体100外部。第一通气口111和第二通气口121同时吸气或吹气，或者第一通气口111和第二通气口121中的其中一者吹气，第一通气口111和第二通气口121中的另一者吸气。在一实施例中，第一通气口111吸气，第二通气口121吹气，用户可以根据实际情况，选择性地将主体100的风嘴110对准待清除灰尘的位置吸收灰尘或者将灰尘吹落。
在一实施例中，电机610能够带动叶轮转动，以驱使第一通气口111和第二通气口121同时吸气或吹气，或者第一通气口111和第二通气口121中的其中一者吹气，第一通气口111和第二通气口121中的另一者吸气。或者电机610能带动叶轮转动以驱使第一通气口111吸气，第二通气口121吹气。
在一实施例中，主体100的第一通气口111和第二通气口121可以连接细长状的气管，主体100可以通过气管吸气或吹气，细长状的气管便于伸入空间狭小的空间清除灰尘，使得清除灰尘更方便有效。气管可以与主体100通过焊接或一体成型等固定方式连接，也可以通过卡接或螺纹连接等可拆卸的方式连接，本实施例的气管与主体100通过卡接的方式可拆卸连接。
如图1所示，具体地，主体100的第一通气口111设置有连接槽112，连接槽112朝向主体100内部延伸，连接槽112连通通气腔102和主体100外部。连接槽112的形状不限，可以为圆形、矩形或椭圆形等形状，本实施例的连接槽112为椭圆形，连接槽112能够与横截面为椭圆形的第一气管700配合插接或者分离。第一气管700背向主体100的一端可以可拆卸插接一个刷件710，刷件710背向第一气管700的一端可以沿刷件710周向设置多个刷毛720，刷毛720能够作用于一些不容易清除的污垢，刷件710为中空状，便于通气，再配合刷毛720更容易清除污垢，使用方便。另外，刷件710背向第一气管700的一面呈倾斜设置，所有刷毛720长度可设置成一致，即多个刷毛720背向刷件710的一端所在平面也为倾斜状，清除污垢更精细方便。
如图2所示，在一实施例中，主体100包括第一壳体130、第二壳体140以及过滤网罩150，第一壳体130和第二壳体140相连接，主体100的第一通气口111位于第一壳体130远离第二壳体140的一端，主体100的第二通气口121位于第二壳体140远离第一壳体130的一端，风机组件600设置于第二壳体140内，过滤网罩150设置于第一壳体130内，并位于风机组件600和第一通气口111之间，气流能够在风机组件600的抽吸作用下经设置在第一壳体130上的第一通气口111进入第一壳体130内，然后依次经过过滤网罩150、风机组件600，最后从设置在第二壳体140上的第二通气口121排出。另外过滤网罩150能够过滤被吸入气流中的杂质，使得从第二通气口121吹出的气流更纯净，在使用第二通气口121吹气除杂时，不会引入新的杂质。
在一实施例中，主体100还包括第一固定部160和第二固定部170，第一固定部160和第二固定部170皆收容于第二壳体140内，且第一固定部160设置于第二壳体140靠近第一壳体130的一端，第二固定部170设置于第二壳体140远离第一壳体130的一端，风机组件600的电机610限位于第一固定部160和第二固定部170之间，以实现对电机610在主体100的中心轴的方向上的限位。在一实施例中，主体100还包括减震垫180，减震垫180设置于第二壳体140内，且减震垫180抵持在第二固定部170和电机610之间，以减小电机610带动叶轮旋转工作时的震动，从而降低电机610工作噪音。
在一实施例中，主体100还包括过滤盖板190，过滤盖板190部分嵌设于第二壳体140远离第一壳体130的一端内，主体100的第二通气口121位于过滤盖板190外露于第二壳体140的一端，过滤盖板190能够进一步隔挡过滤之后的气流中的杂质，使得从第二通气口121吹出的气流更纯净，在使用第二通气口121吹气除杂时，不会引入新的杂质。
手柄200内部设有电路板240，电路板240用于控制风机组件600的运行与停止，从而驱使第一通气口111和第二通气口121吹气或吸气除尘。进一步地，手柄200的侧壁上设置有控制按键250，且控制按键250电连接电路板240，操作者可以手动操控控制按键250，以控制控制风机组件600的运行与停止，从而驱使第一通气口111和第二通气口121吹气或吸气除尘。
在一实施例中，手柄200内部还设置有电池260，电池260与除尘机10的各用电机构电连接，电池260用于给除尘机10的各用电机构进行供电。具体地，除尘机10的用电机构可以但不限于包括电机610和电路板240。
在一实施例中，手柄200的侧壁上设置有充电接口270，且充电接口270电连接电池260，充电接口270用于给电池260进行充电，具体地，充电接口270通过电路板240与电池260电连接。如图3所示，在一实施例中，手柄200包括相对接的第一基壳231和第二基壳232（即手柄壳体200a），具体地，第一基壳231和第二基壳232通过螺纹紧固件可拆卸固定连接，电路板240及电池260收容于第一基壳231和第二基壳232围合形成的空腔内。
在一实施例中，手柄200还包括端盖233，端盖233与手柄壳体200背向主体100的端部连接，以将电路板240和电池260限位于手柄200内部。
在一实施例中，参考图4，手柄200背向主体100的端部设置有散热结构280，散热结构280包括周向布置的散热孔281，散热孔281连通手柄200内部与手柄200外部。一实施例中，手柄200内部与主体100内部连通，主体100用于安装能够实现风嘴110吹气或吸气的风机组件600，风机组件600能将气流引导至手柄100内部并由散热孔281排出。可以理解，在其它实施例中，也可以单独安装一组鼓风机，以建立手柄200内部的气流流动，使得手柄200内部的气流流动能够带走手柄200内部电路板240和电池260工作产生的热量，携带热量的气流能经由手柄200底部的散热孔281扩散到外界。
本发明实施例的除尘机10，用户能够通过手握手柄200来利用主体100内的风机组件600进行吹气和吸气以完成除尘。在除尘的过程中，由于手柄200背向主体100的一端设置有散热结构280，从而手柄200内部的气流能够能够经散热结构280流程手柄200外部，以完成对手柄200内部的电路板240、电池260和其他电子器件的散热。并且，由于散热结构280包括周向布置的散热孔281，使得气流能够向四周均匀扩散，增强散热效果。另外，用户握持手柄200来使用时，热流由手柄200端部流出，不会烫手。
在一实施例中，散热结构280包括环形的散热圈282，散热圈282包括多个沿周向间隔排布的散热孔281。可以理解，在其它实施例中，周向排布的散热孔281可以相互连通，此时散热圈282在手柄200周向连续设置。
图4示意了散热圈282的数量为至少一个，至少一个散热圈282围绕手柄200的侧表面设置。例如图4示意了散热圈282的数量为两个，两个散热圈282沿手柄200的长度延伸方向间隔排布，当然，在其它实施例中，设置在手柄侧表面上的散热圈282的数量还可以为两个以上，本申请不作限制。
手柄200侧表面设置的散热孔281具有孔壁，散热孔281的孔壁所在表面倾斜手柄200的径向，如此设计，可以使得热流经散热孔281排出后形成旋涡状产生涡流，更有利于吸引手柄200内部热量的进一步排至手柄200外。
在其它实施例中，参考图5，至少一个散热圈282设置于手柄200背向主体100的底部端面。此时热流能够由手柄200的底部端部朝下流出，这可以避免用户手握手柄200进行使用时，侧向流出的热流喷射到人体导致烫伤。本申请还可以同时在手柄200侧壁和手柄200底部端面同时设置散热圈282。
在一实施例中，参考图6，手柄200在背向主体100的端部设置有隔腔283和进风口284，进风口284横向连通手柄200内部与隔腔283，手柄200背向主体100的底部端面设置的散热孔281与隔腔283连通。如此设计，来自于手柄200上端扩散而来的热流（气流携带有电路板240工作时散热的热量）不会直接喷射到外界，热流能够受到手柄200底部的抵挡而改变流动方向，热流能够横向经进风口284扩散至隔腔283，再经隔腔283由散热孔281扩散到外界，手柄200上端冲击而下的热流的流速得到大大减缓，速度大大减缓的热流即使意外喷射到人身上，也不会轻而易举受到热流冲击伤害。
在一实施例中，手柄200包括壳体200a和端盖233（参考前文所述），壳体200a与主体100连接并呈夹角设置，壳体200a远离主体100的端面设置有周向间隔排布的多个凸起285，端盖233开设有散热孔281，端盖233盖合于壳体200a并抵接凸起285，以围合形成隔腔283和进风口284。
虽然已参照几个典型实施方式描述了本发明，但应当理解，所用的术语是说明和示例性、而非限制性的术语。由于本发明能够以多种形式具体实施而不脱离发明的精神或实质，所以应当理解，上述实施方式不限于任何前述的细节，而应在随附权利要求所限定的精神和范围内广泛地解释，因此落入权利要求或其等效范围内的全部变化和改型都应为随附权利要求所涵盖。
